Haplotypes of [-794(CATT) /-173G>C] MIF gene polymorphisms and its soluble levels in cutaneous squamous cell carcinoma in western Mexican population.

Background: Some cytokines are strongly implicated in the development of squamous cell carcinoma (SCC) such as the Macrophage migration inhibitory factor (MIF).

We present four cases of nevoid acanthosis nigricans localized to the umbilicus; in patients less than 25 years of age, with no known co-morbidities, three of whom were females.

Genetic biomarkers related to hemarthrosis, inflammation, and cartilage structure in pediatric patients with hemophilic arthropathy.

Background: The pathophysiology of hemophilic arthropathy is complex and not completely understood. In this study, we aimed to identify biomarkers that can affect the hemophilic arthropathy severity.

Methods: Fifty patients were analyzed for biomarker frequencies; in 37 patients, articular symptoms were evaluated based on the physical joint examination score, and in 18, it was based on magnetic resonance imaging.

Basal cell carcinoma, blue-white variant: Dermatoscopic findings in 32 cases.

Background: The diagnosis of basal cell carcinoma is histopathological, but there are dermatoscopic criteria that confer high sensitivity and specificity to help the clinician improve its identification. However, the basal cell carcinoma blue-white variant does not totally meet these dermatoscopic criteria, and thus can be confused with other pigmented tumors. In the literature reviewed, we found only five cases of this variant.
